Role of Exosomes in the Progression, Diagnosis, and Treatment of Brain Tumors
Vaníková, Lucie ; Zíková, Martina (advisor) ; Lacina, Lukáš (referee)
Recent studies have confirmed the importance of extracellular vesicles, particularly exosomes, in the development of brain tumors. Considerable attention has been paid mainly to the influence of exosomes on biological processes in brain tumors. Exosomes mediate intercellular communication in the tumor microenvironment by transporting biomolecules. Most often they transmit various types of ribonucleic acids, specifically microRNAs, which affect the signalling pathways related to tumour growth in target cells. Thus, exosomes play an important role in tumor cell proliferation and differentiation, metastasis, and tumor resistance to chemotherapy or radiation. Due to their small size, exosomes can cross the blood-brain barrier and thus promote tumor progression. The topic of the bachelor thesis is a summary of the current knowledge on the role of exosomes in brain tumor progression, diagnosis and treatment.
